The National Institute for Aviation Research (NIAR) conducts a wide range of safety-related coupon and full-scale impact testing for many applications with a variety of projectiles and test specimen material designs, such as:

  • Aircraft bird strike and hailstone impact resistance
  • Windborne debris
  • Turbine engine fragmentation
  • Pressure vessel impact and containment
  • Ballistic and Impact resistant structure qualification

The Ballistics Test Facility contains a control/instrumentation room and a target room/bunker. The
range is setup so that targets can be located at 25, 50, 75, and 100 feet from the gun. Adjustability
is available that provides quick vertical and horizontal adjustments of the target position.

The Large Compressed Gas Gun can perform bird strike testing from 60-knot rotary-wing FAA
Airworthiness Certification up to >550-knot fixed-wing USAF canopy qualification testing.

Projectiles, sabots, and target fixtures are often designed, constructed and tested at NIAR to meet a
client鈥檚 specific need. A suite of state-of-the-art data acquisition and computer controls supports the
experimental facilities.
